Abstract
A fully automated microextraction by packed sorbents (MEPS) coupled with large volume injection gas chromatography-mass spectrometry (GC-MS) has been developed for the determination of eight polycyclic aromatic hydrocarbons (PAHs) in environmental water samples. Naphthalene (Nap), pyrene (Pyr), anthracene, acenaphthylene, phenanthrene, fluoranthene (Flr), fluorene and acenaphthene were the PAHs studied. The performance of the microextraction-GC-MS protocol was compared with solid phase extraction (SPE) and GC-MS analysis. Under optimized experimental conditions, the methods were linear for all analytes in the following ranges: 0.05-2.0 mug L(-1) (MEPS) and 0.25-10.0 mug L(-1) (SPE). The correlation coefficients (R(2)) were in the range 0.9965-0.9997 (MEPS) and 0.9978-0.9998 (SPE) for all the analytes. Limits of detection (LODs) for 2 mL samples (MEPS) ranged from 0.8 ng L(-1) to 8.2 ng L(-1). LODs for 50 mL samples (SPE) were between 4.8 ng L(-1) and 35.9 ng L(-1). The two methods were successfully applied to the determination of the 8 PAHs in environmental waters, with recoveries in the range of 70-117% (MEPS) and 72-134% (SPE) for a real spiked sample. The two sample preparation processes showed good repeatabilities with intra-day relative standard deviations below 14.0% (MEPS) and 14.6% (SPE). Nap, Flr and Pyr were found in a river water sample.

Abstract
BACKGROUND: Jiang-gua (fermented cucumbers) is a popular traditional fermented food in Taiwan. The microflora of lactic acid bacteria (LAB) in jiang-gua have not been investigated in detail. In this study, LAB from jiang-gua were isolated, characterised and identified. RESULTS: A total of 103 LAB were isolated; 70 cultures were isolated from jiang-gua samples and 33 cultures were isolated from its raw substrate, cucumber. These isolates were mainly characterised phenotypically and then divided into seven groups (A-G) by restriction fragment length polymorphism analysis and sequencing of 16S ribosomal DNA. The isolates were identified as Enterococcus casseliflavus, Leuconostoc lactis, Leuconostoc mesenteroides, Lactobacillus pentosus, Lactobacillus plantarum, Lactobacillus paraplantarum, Lactococcus lactis subsp. lactis, Weissella cibaria and Weissella hellenica. The antibacterial activities of the isolates were determined and 11 Lc. lactis subsp. lactis strains showed inhibitory activity against the indicator strain Lactobacillus sakei JCM 1157(T) . CONCLUSION: Heterofermentative W. cibaria and Leu. lactis were the major LAB found in jiang-gua samples without soy sauce. In soy sauce-added samples, homofermentative L. pentosus and L. plantarum were the most abundant LAB. In addition, the results also suggested that HhaI and RsaI restriction enzymes could be applied to distinguish W. hellenica and Weissella paramesenteroides.

Abstract
AIM: To investigate the incidence of gastroesophageal reflux disease (GERD) and its related risk factors in Uygur and Han Chinese adult in Urumqi, China. METHODS: A population-based cross-sectional survey was undertaken in a total of 972 Uygur (684 male and 288 female) aged from 24 to 61 and 1023 Han Chinese (752 male and 271 female) aged from 23 to 63 years. All participants were recruited from the residents who visited hospital for health examination from November 2011 to May 2012. Each participant signed an informed consent and completed a GERD questionnaire (Gerd Q) and a lifestyle-food frequency questionnaire survey. Participants whose Gerd Q score was >/= 8 and met one of the following requirements would be enrolled into this research: (1) being diagnosed with erosive esophagitis (EE) or Barrett's esophagus (BE) by endoscopy; (2) negative manifestation under endoscopy (non-erosive reflux disease, NERD) with abnormal acid reflux revealed by 24-h esophageal pH monitoring; and (3) suffering from typical heartburn and regurgitation with positive result of proton pump inhibitor test. RESULTS: According to Gerd Q scoring criteria, 340 cases of Uygur and 286 cases of Han Chinese were defined as GERD. GERD incidence in Uygur was significantly higher than in Han Chinese (35% vs 28%, chi(2) = 11.09, P

Abstract
INTRODUCTION: Foam sclerotization of varicose veins may cause paradoxical embolization through patent foramen ovale (PFO). The aim of our study was to: 1) select an optimal screening method for the detection of PFO; 2) determine the prevalence of PFO in a non-selected population; and 3) test the risk of paradoxical embolization of venous bubbles in patients with PFO. MATERIALS AND METHODS: A diver after decompression is a suitable model for determining the risk of paradoxical embolization of venous gas bubbles. 329 Czech divers were screened for PFO. In a pilot study, we compared Transcranial Doppler Sonography (TCD) with Transesophageal Echocardiography (TEE) in 100 patients. TCD alone was used for further screening. In 31 divers with PFO, nitrogen bubbles were detected after simulated dives. Transthoracic Echocardiography (TTE) was used to detect venous bubbles in right-sided heart chambers; TTE and TCD were used to detect arterial bubbles. The right-to-left shunt was rated as non-significant (

Abstract
BACKGROUND & AIMS: Cigarette smoking has been implicated in the etiology of esophageal adenocarcinoma, but it is not clear if smoking is a risk factor for Barrett's esophagus. We investigated whether tobacco smoking and other factors increase risk for Barrett's esophagus. METHODS: We analyzed data from 5 case-control studies included in the international Barrett's and Esophageal Adenocarcinoma Consortium. We compared data from subjects with Barrett's esophagus (n = 1059) with those from subjects with gastroesophageal reflux disease (gastroesophageal reflux disease controls, n = 1332), and population-based controls (n = 1143), using multivariable logistic regression models to test associations with cigarette smoking. We also tested whether cigarette smoking has synergistic effects with other exposures, which might further increase risk for Barrett's esophagus. RESULTS: Subjects with Barrett's esophagus were significantly more likely to have ever smoked cigarettes than the population-based controls (odds ratio [OR] = 1.67; 95% confidence interval [CI]: 1.04-2.67) or gastroesophageal reflux disease controls (OR = 1.61; 95% CI: 1.33-1.96). Increasing pack-years of smoking increased the risk for Barrett's esophagus. There was evidence of a synergy between ever-smoking and heartburn or regurgitation; the attributable proportion of disease among individuals who ever smoked and had heartburn or regurgitation was estimated to be 0.39 (95% CI: 0.25-0.52). CONCLUSIONS: Cigarette smoking is a risk factor for Barrett's esophagus. The association was strengthened with increased exposure to smoking until approximately 20 pack-years, when it began to plateau. Smoking has synergistic effects with heartburn or regurgitation, indicating that there are various pathways by which tobacco smoking might contribute to development of Barrett's esophagus.

Abstract
SETTING: While waterpipe and cigarette smoking have been well studied in Syria and Lebanon, data from Jordan are limited. OBJECTIVES: To characterize the relative prevalence of waterpipe tobacco and cigarette smoking among university students in Jordan, and to compare the demographic and environmental factors associated with each form of tobacco use. DESIGN: We surveyed 1845 students randomly recruited from four universities in Jordan. We used multivariable logistic regression controlling for clustering of individuals within universities to determine associations between demographic and environmental covariates and waterpipe tobacco and cigarette use. RESULTS: Waterpipe tobacco smoking rates were 30% in the past 30 days and 56% ever, while cigarette smoking rates were 29% in the past 30 days and 57% ever. Past 30-day waterpipe tobacco smoking rates were 59% for males and 13% for females. Females had substantially lower odds than males of being current waterpipe (OR 0.12, 95%CI 0.10-0.15) or cigarette (OR 0.08, 95%CI 0.05-0.14) smokers. Current cigarette smoking was more significantly associated with markers of high socio-economic status (SES) than waterpipe tobacco smoking. CONCLUSION: Waterpipe tobacco smoking is as common as cigarette smoking among Jordanian university students. While cigarette smoking is consistently associated with high SES, waterpipe tobacco smoking is more evenly distributed across various populations.

Abstract
Although the pathogenesis of cervical inlet patch (CIP) is not fully understood, most authors consider it as a congenital abnormality, whereas others surmise it to be related to gastroesophageal reflux disease (GERD). We aimed to evaluate esophageal function and the prevalence of GERD and Barrett's esophagus in patients with CIP. GERD is defined by the presence of erosive esophagitis or an abnormal pH monitoring. Seventy-one consecutive patients with endoscopic and histological evidence of CIP were prospectively evaluated. Esophageal symptom analysis, 24-hour simultaneous biliary reflux and double-channel pH-monitoring, and esophageal manometry were carried out in 65/71 (92%) patients and in 25 matched controls. Six patients were not suitable for testing and were, therefore, excluded. The histological evaluation of the heterotopic islands showed cardia and/or oxyntic mucosa in 64/65 (98%) patients and specialized intestinal metaplasia (SIM) in one patient (2%). The cardia and/or oxyntic mucosa was accompanied by focally appearing pancreatic acinar metaplasia and pancreatic ductal metaplasia in 7/64 (11%) and in 1/64 (2%), superficial mucous glands in 6/64 (9%), and SIM in 2/64 (3%) cases. In total, SIM was present in three patients (5%), and one of them had low-grade dysplasia. At the gastroesophageal junction, 28 (43%) patients had columnar metaplasia, including nine (14%) patients with SIM. Erosive esophagitis was present in 37 (57%) cases. Thirty-two patients (49%) had abnormal acid reflux in the distal and 25 (38%) in the proximal esophagus. Abnormal biliary reflux was present in 25 (38%) cases. On the basis of endoscopic and pH studies, GERD was established in 44/65 (68%) patients. Typical reflux symptoms were common (33/65, 51%). The combined 24-hour biliary and double-channel pH-monitoring detected significantly more significant acidic reflux at both measurement points and significantly longer bile exposure time in the distal esophagus in patients with CIP. Acid secretion in the CIP was detected in three (5%) cases. Esophageal manometry revealed decreased LES pressure and prolonged relaxation with decreased peristaltic wave amplitude, and an increased number of simultaneous contractions in the esophageal body. The detailed evaluation of the esophageal morphology and function in subjects with CIP showed a high prevalence of GERD and Barrett's esophagus. Further studies are needed to evaluate whether combined acidic and biliary reflux is able to promote similar histomorphological changes in the CIP, as it is shown distally in patients with Barrett's esophagus.

Abstract
INTRODUCTION: This study aims at evaluation of the effect of smoke-free policy at hospitality workplaces on indoor air quality. MATERIALS AND METHODS: Study includes 151 hospitality venues (restaurants, cafes, bars and tea-houses) at eight provinces of Turkey. PM2.5 measurements were done at each of the venues three months prior to, and 4-5 months after the implementation of smoking ban at the same venues. Measurements were done using SidePak 2.5 by two engineers. During the 30 minutes of measurement, the device takes multiple samples, measures PM2.5 particles, and calculates the average value and standard deviation of the measurements. RESULTS: Using the measurement results two kinds of evaluation were done: in each province, increase/decrease after implementation for each of the venues included in the study was evaluated, and average PM2.5 values were calculated for provinces using the PM2.5 values of the venues in the province. The average PM2.5 values before the implementation were higher than the post implementation values in general. Nevertheless, in some provinces higher values were found during the second measurements, particularly at the restaurants. CONCLUSION: Therefore, there is need to enforce the smoking ban at the hospitality workplaces.

Abstract
Nanogels based on chitosan and cashew gum were prepared and loaded with Lippia sidoides oil. Several parameters such as cashew gum concentration and relative oil content in the matrix had their influence on nanogel properties investigated. Nanogels were characterized regarding their morphologies, particle size distributions, zeta potential, Fourier transform infrared spectroscopy and essential oil contents. The release profile was investigated by UV/vis spectroscopy and its efficacy was determined through bioassays. Results showed that samples designed using relative ratios matrix:oil 10:2, gum:chitosan 1:1 and 5% gum concentration showed high loading (11.8%) and encapsulation efficiency (70%). Nanogels were found to exhibit average sizes in the range 335-558 nm. In vitro release profiles showed that nanoparticles presented slower and sustained release. Bioassays showed that larval mortality was related mainly to oil loading, with samples presenting more effective larvicide efficacies than the pure L. sidoides oil.

Abstract
BACKGROUND: Our aim was to assess second-hand smoke (SHS) exposure in hospitality venues after the smoke-free legislation implemented in September 2010 in Greece and to compare with when a partial ban was in place and in 2006 when no ban was in place. METHODS: Hospitality venues were prospectively assessed for their indoor concentrations of particulate matter (PM(2.5)) during the partial ban phase (n=149) and the complete ban phase (n=120, 80% followed up), while overall and matched by venue comparisons were also performed (no ban vs. partial ban vs. complete ban). Comparisons with previously collected data in 2006 when no ban was in place also was performed. RESULTS: Indoor air levels of PM(2.5) attributable to SHS dropped following the transition from a partial to a complete ban by 34% (137 mug/m(3) vs. 90 mug/m(3), p=0.003). This drop was larger in bars (from 195 mug/m(3) to 121 mug/m(3)), than in cafes (124 mug/m(3) vs. 87 mug/m(3)) or restaurants (42 mug/m(3) vs. 39 mug/m(3)). PM(2.5) concentrations between 2006 (no ban) and the partial ban of 2010 were also found to decrease by 94 mug/m(3); however, among matched venues, the levels of indoor air pollution were not found to change significantly (218 mug/m(3) vs. 178 mug/m(3), p=0.58). Comparing the 2010 complete ban results (n=120) with previously collected data from 2006 when no ban was in place (n=43), overall PM(2.5) concentrations were found to fall from 268 mug/m(3) to 89 mug/m(3), while a matched analysis found a significant reduction in PM(2.5) concentrations (249 mug/m(3) vs. 46 mug/m(3), p=0.011). CONCLUSION: The complete ban of smoking in hospitality venues in Greece led to a reduction in SHS exposure, in comparison to when the partial ban or no ban was in place; however, exposure to SHS was not eliminated indicating the need for stronger enforcement.
